Abstract: In a connection between spinning and winding machines, in which a plurality of different yarn batches are to be processed, it will be additionally possible to conduct a check of the spinning stations in respect of the quality of the cops produced. According to the invention, the information on the spinning station which has produced the particular cop is connected to the associated pallet by means of a readable information carrier. Different colours of the cop tubes corresponding to the particular yarn batch are detected by colour sensors arranged in a common feed system. These sensors guide the cops together with their pallets into the winding portions assigned to the respective yarn batches. The cops which exceed a predeterminable number of yarn breaks during unwinding are identified accordingly in the winding station. This identification is subsequently detected by a sensor which activates an adjacent reading device. <IMAGE>

Abstract: Regions (13, 14) having different impurity concen­trations are formed in the main surface region of the semiconductor substrate (10). Accordingly, when the substrate is oxidized, oxide films (15, 16) having dif­ferent thickness are formed. More specifically, the oxide film is formed more deeply on the surface region of the substrate having a high impurity concentration in which ions are injected than on the surface region in which no ions are injected. In the etching step, since the thinner oxide film (16) is removed while the thicker oxide film (15) remains, the surface of the region (14) under the thinner oxide film is exposed, and thus a contact hole is formed. If, in the step of forming a contact hole, a portion of the thinner oxide film (16) is covered by a resist pattern, only the region of the oxide film which is not masked by the resist pattern is etched and the substrate surface thereunder is exposed, and thus a contact hole is formed.

Abstract: Skirting board having a wooden-material core which is covered by an extruded-on hot-melt adhesive layer and an outer layer, extruded onto the latter, of a thermoplastic and contains, to prevent elongation of the mounted skirting board, a hygroscopic salt and, in the delivery state of the skirting board, a quantity of water exceeding the natural water content of the wooden material. To manufacture such a skirting board in a continuous process, the wooden-material core is, in a continuous process, first sprayed with water and heated and then impregnated with a salt solution by supplying the latter, under pressure, on one side of the wooden-material core strip and applying a vacuum on the opposite side of the core strip, whereupon the hot-melt adhesive layer and the outer layer are extruded onto the core layer before its elongation caused by the impregnating agent has reached its maximum. <IMAGE>

Abstract: In a computer system, when after voltage supply to individual components is inhibited by depression of a power supply switch (45), the power supply switch (45) is depressed again for the voltage supply, a power supply controller (50) determines whether or not a predetermined period of time has elapsed after the voltage supply is inhibited. Upon elapse of the predetermined period of time, the voltage supply to the individual components starts. In the case where a voltage is being supplied to the individual components by depression of the power supply switch (45), when the power supply switch (45) is depressed again to inhibit the voltage supply, it is determined whether or not a resume process has been completed, or a predetermined period of time has elapsed from the beginning of the voltage supply. When the resume process has been completed, or the predetermined period of time has elapsed from the beginning of the voltage supply, the voltage supply to the individual components is stopped.

Abstract: In previous electronic devices, functional differences in the equipment features were achieved by producing a multiplicity of different types of device. This multiplicity of types entails a high outlay in terms of production for the manufacturer of the devices. Furthermore, for the customer, the devices often have the disadvantage that he must buy a device having equipment features which he never uses, but still has to pay for at the time of purchase. By the use of a data carrier card which allows an individually desired activation of device functions, it is possible to restrict the multiplicity of types during production. <IMAGE>

Abstract: In a television pick-up and display system comprising a pick-up device having an image pick-up face whose aspect ratio deviates from an aspect ratio of the image display face of the image display device, the pick-up device can be rendered suitable for cooperation with the image display device by insertion of an anamorphotic optical system between an object plane and the image pick-up face. When use is made of an image pick-up face having a 4:3 aspect ratio and an image display face having a 16:9 aspect ratio, the anamorphotic optical system compresses an image of the object plane in the horizontal direction by a compression factor amounting to 0.75. When the compressed image of the image pick-up face is displayed, an image-filling, non-distorted image is obtained on the image display face.
